ROSEMOUNT 3300
CHEMICAL
Inclined Installation with Guided Wave Radar
Enables Hexane Level Measurement
RESULTS
• Enables a level reading from the side of the vessel.
• Provided tighter process control resulting in higher quality end product
• Accurate and reliable level readings independent of density changes
APPLICATION
Liquid Hexane Level for Palm Oil Production
Application Characteristics: Clean, low dielectric fluid (1.9),
some density variation, non-standard tank shape.
CUSTOMER
The increased reliability and
accurate measurement
provides tighter process
control, resulting in higher
quality in the end product.
Eco Oils Sdn Bhd, in Malaysia
CHALLENGE
In an expansion project at Eco Oils Sdn Bhd in Malaysia, palm oil is
extracted in a unique filtration process developed and engineered for the
first time in the world.
The level in this evaporator is always maintained in the bottom portion at
less than 4 meters (13.2 ft).
On these hexane evaporators there is neither a top-mounting nozzle for a
top-down instrument nor a bottom nozzle for a differential pressure
transmitter.
The customer also was concerned about the varying density of hexane.
Maintaining the correct level in this evaporator is critical to maintain the
flow of hexane to the next process.
SOLUTION
It was determined that there was a possibility to mount a gauge at an
inclined position of 35° in the lower portion of the vessel where the hexane
level was to be maintained.
The Rosemount 3300 Guided Wave radar (GWR) transmitter
seemed like a great option for accurate level measurement.
The transmitter is suitable for a variety of different tank shapes
and sizes. The use of a rigid probe mounted in the side of the
tank at an angle allowed this normally top-down technology to
be used in this installation. The installation angle was
configured into the gauge using Radar Configuration Tools.

10 m (33 ft.)
4 m (13 ft.)
Hexane evaporator with no top-mounting nozzles
and no space in the bottom.
CHEMICAL
This allowed the 3300 to make a correction to obtain the accurate vertical
level height. Because radar is immune to density changes, no additional
corrections were needed. The increased reliability and accurate
measurement provides tighter process control, resulting in higher quality in
the end product.
The customer now has a reliable hexane measurement.
Inclined installation at 35° of Rosemount 3300 gives
the customer a reliable level reading from a
non-standard tank shape.
With Radar Configuration Tools, compensation for a mounting angle is easy.
